Frequently asked questions
What is the difference between the two encode modes?
Component mode (encodeURIComponent) encodes every reserved character, which is right for a single parameter value. Full-URL mode (encodeURI) leaves the characters that structure a URL alone.
Why do spaces sometimes become +?
HTML forms encode spaces as + in query strings. Decoding here treats + as a space when the “form encoding” option is on.
